of which theoliowing deseriptien, in eenv neetion with the accompanyingdrawing, is a specification, like eharaeters en the firmwlo ingsrepresenting like parts.

. This invention relates to improvements in tlre class of sheet feedingapperetns described in United 4States Paient No. 748,219, dated Eeeembe29, 1903, the ebjeei o the present invention being to render easier andmore certain the operation of the combing` wheel or other device infeeding the sheets continuously one after the other from the top of apile of sheets, it being understood Ythat when a sheet. fails to bepresented to the usual guides of the press to which Ythe sheets aresupposed to be ed, the press will be stopped. V

In the patent referred te the sheets of the pile of sheets against whichthe combingwheel acts are maintained in a horizontal. positionY andconsiderable pressure ,is required to be exerted through the wheel sostart the to -sheet `ef the pile, and with thin sheets t e pressurerequired for startm the top sheet 'from the pile of horizontal y laidsheets is suiiicient ai; times to in-Y jure and wrinkle the paper.

I have discovered by experiment that the sheets may he unerringly fedYfrom the pile by less pressure of the combing-Wheei on the: top-sheet ofthe pile, and without liability of injuring the-sheet, ii the supportsustaining the pile of sheets is located in such 40 position that thesheets inciine forwardly and downwardly toward the inelined side of theridge, as inse doing the tendency of each sheet to slide down and effthe pile is made evaiable to iessen the Yfrietiien to be overcome instartinfjeach from the top of the pile, and as sie friction of in@ mostsheet en the sheet below it less electrieai influence is set np remevaiof the successive sheets.

The drawing shows assueien portion of a sheet feeding apparatus, with myimprovements added, te enable my inenien to be fzleseribedl The A'upperis reduced, dining the having the incline-df face e combing wheel'A ere enti may be all as fully described in United Stetes--Peient-ele.48,2i9, dated Beeeniher 29, 9E-3i In that ment ne ridge has e sioi iand'inimedieteiy below the apex ei the ridge i is jenrnaieri e reeir she'te which is red en erin. 8 earrying e piae that. is yidingly snsreinein the sint o ehe ridge. rsfte eornbing wheel .acts on the tepY sheeefthe i pileit projects said sheet orwardiyentii the front erige strikesthe inelined snifeee oatiie ridge, said sheef; et this time being bentdownwardly slightly by its own weight.l The veelfiiainned movement nfelle eombing wheei Y pushes the frentvedge of *tre sheeting@V theineiined surface ei the ridge until aetai npon by the feeding wheeiwhieir operating Y in'conjunction withithe plate carried by the armsoperates to feed the front portion of lthe ,sheet faster than 'theportion acted onby the eolnbing wheel whereby the sheet is straightenedand lifted from the remaining sheets.

In the present appiicatien I employ es Vstated above the ridge hevingthe inclined facets, and I else employ the feeding wheel i 6 locatedabove the peek of the ridge. In Iny presi-:ntL invention, iroweventheerm 8 pivoted 'to the shaft 'i earri'esea relier l2 instead of the,plete above referred to, said miler receiving the ieee-ling edge oi 1thesheet on its way te be grasped by the feeding relier 6 whereby the sheetis acted npon and fed forward by 'the two roli-ers. Moreover in myinvention the top of the support B sustaining the pile of sheets B isnot arranged horizontally as previded i'or in said patent, i but isinstead inclined downwardly inthe direction of the ridge plate, and thereside is L that the top sheet of the pile Qceupiese plane whichinclines downwardly toward the inciined face a ef the ridge, the pieneof the meets the face e etY e peint ediacent the lewer edgeY thereof.The restait of thiseensfruetien is that since the sheets eik oeenpy einin# the top of the pilewhieh ere above the lower edge of theinelinedsnrfeee iisY 5o slide te: Y ward the eidge top sheet isircted upon bythe combing wheei so that eiess amoent of rictierr is: :requiredVbeiween the combing wheei and top sheel te effect theVA 'feeding ofthesheets. Finether, es the sheets are projeeted' ferwendl, es shewn in thedrawings, lthe 'ent edges iieree ,strike the inelineel i suriee e oftheridge at a aint nearer he bese than possible with t deviee shown topsheet having sneh en inclination that it i 10e I elined piane, thetendency 'ef those sheets at in the patent referred to above, andconsequently as the front edges of the sheetsslide up the inclined facea of the ridge and are then grasped by the feeding wheel'6 more' room-isprovided'for the various sheets to separateto permit air to enterbetween them. This results in eliminating to a great extent the tendencyof the sheets to stick together and provides an Aapparatus by means ofwhich the sheets can be more readily and acwith the device shown in thepatent above referred to.

Having described my invention what I claim as new and desire to secureby Letters Patent' is 1. In an apparatus of the class described, a ridgehavingan inclined surface, a support for a pile of sheets of paperhaving its top surface inclined downwardly toward the ridge, and acombing wheel to act on they up- `Y permost sheet of the pile andstartit toward the ridge,the inclination of the support for the pile ofVsheets being such that the/tof support 'for a pile of sheets ofpapr,said its to occupying a plane insupport havin ly .an downwardly from aclined forwar horizontal plane, and a ,combing wheel acting upon tpeuppermost sheet of the "pile, vcombined""wi th an inclined :ridge andtwo rollers to which the end of the topmost sheet leaving the pile andrpassing up the incline is delivered, the rotation of the wheels at theapex of the incline aiding Ain taking the topmost sheet rfrom the` topof the pile.

In testimony whereof, I have signed my name to this specification, inthe presence o two subscribing witnesses.
